Your very own cell tower

There are a variety of products out there for increasing cell phone coverage inside buildings - from gimmicky foil battery "enhancers" to external antennas, but SpotWave has announced their new ZEN repeater product. SpotWave manufactures enterprise-scale cellular repeaters so I'm led to believe this product will actually work. If it works as advertised, at $399, it is fairly inexpensive compared to similar products on the market.
